The "Marry Feng" tattoo on the wrist is a lifelong vow made by young Zhou Qi to Wu Xin. When they reunited after eleven years, he thought that what was waiting for him was the rekindling of his old love, but he didn't know that it was a carefully planned farewell. It turns out that her heartlessness back then was just to keep him alive. This is a deeply affectionate sadomasochism film adapted from real experiences, telling a story about guarding, missing, and a regretful love that lasts until death.
